Influence

The ArchiMate model illustrates the use of the influence relationship for making a trade-off between the two requirements that realize the goal Improve portfolio management. The goal Increase customer satisfaction and the principle Systems should be customer facing are used as trade-off criteria. Both requirements positively influence the intended increase of customer satisfaction. The requirement of using a personal assistant scores a little better for this criterion. However, the requirement scores a lot worse for the customer-facing criterion. The positive score of the requirement Provide on-line portfolio service for the customer-facing principle is consistent with the description of the requirement realizing the principle in an earlier example.
